Glad I was not camping

Bob, I’m certainly not an expert on heat pumps, as while we have them.....we’ve never used them. My limited knowledge consists of a solenoid, downstream of the compressor, which directs ( changes direction of refrigerant flow) the hot discharge to the condenser for cooling ( ac use), or to the inside of the camper. I do know, if the solenoid fails in the ac mode, the outside finned area will get hot ( hot gas is passing through coils to cool)....if failed in the heat pump mode, the outside coils will get cold!

Many compressors ( not sure about) have a low level/volume shutdown to protect the compressor. If your system has said shut-down, perhaps you are low on refrigerant. Most/many/all camper ac units are not designed for a refill of refrigerant! If that is the case, I’ve heard (can’t verify), that some “techs” can install a fill (schrader type) valve in the system for a refill.

I hope that I’m not too far off on my understanding of the ac/heat pump system. Maybe someone can chime in and correct my errors.

As I said it wes 46.....the first vent had a temp of 93 then the compressor immediately shut off. The compressor did not run long enough to raise the temp in the camper....

the compressor does not run long enough to affect the thermostat..
Something is turning off the compressor...

Maybe it's too cool for the heat pump to be able to run continuously without the outside unit freezing up? There's a limit to how much heat it can extract from relatively cold air.

Bob, you may not want to make a fall camping trip with us. 46 F would be an unseasonably warm daytime high. Plus.....you have difficulty finding a “Current Bush” to plug into! ;)

On a more serious note, are you saying that the compressor is “cycling”, rather than staying engaged?

If you run the forced air furnace....does the inside temperature match that of the thermostat setting?

Yes on propane heat the thermostat works fine...the heater is located under the bathroom and over heats the bathroom and bedroom and makes enough noise to wake the dead...

Sixty four is a great temperature for inside a trailer. A lot warmer than my house in the morning.
